ruby on rails - Add I18n translations to rspec tests

Question

How can i add a translation test to my specs ? Something like :

flash[:error].should == I18n.translate 'error.discovered'

this does not work of course. How to make it work ?

I want to make sure that i get a certain error back.

Answer 1

In my code, a Rails 3 project, using RSpec 2, that is exactly the line I write:

describe "GET 'index'" do
  before do
    get 'index'
  end
  it "should be successful" do
    response.should be_redirect
  end

  it "should show appropriate flash" do
    flash[:warning].should == I18n.t('authorisation.not_authorized')
  end
end

So I am not sure why you say it is not possible?
